INSECT-DESTROYER.

To all whom,- it may cancer-a;

vBe itknown that l, GEORGE W. CAMERON, a citizen of the United States, residing at Hondo, in-the county of Medina and State of Texas, 'have invented certain new and useful Improvementsv in Insect-Destroyers,

of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to insect destroyers, and particularly to means for destroying insects on such. crops as cotton, potatoes and *the like.

The general object of the invention is to provide'an incinerator which is adapted to be drawn over the ground between the rows of plants and is in the form of an oven,.

vent the plants from coming-in contact with the highly heated oven of the incinerator.

Still another object. is to provide means whereby this incinerator may be connected to and mounted upon a cultivator frame and drawn thereby.

A further object is to provide an improved type of burner for the incinerator wherein the fuel i highly heated before the ignited fuel is discharged upon the ground.

A further object is to provide an incin- I erator of this character wherein the clownwardly projected flame from the burner is directed against the earth and by-the earth is deflected laterally so as to spread over the entire surface'defined bythe oven'wallsh .Uther objects will appear in the course of the following description.

My: invention is illustrated in the accompanying drawings, wherein Figure l is a top plan'view of a cultivator with my incinerator or insect destroyerconnected thereto; y

Fig. 2 1s a side elevation'of the cultivator and ncinerator;

Fig." 3 is a rear view of the cultivator,

the incinerator being-shown in section and showing the action of the flame;

Fig. 9 i -a fragmentary side elevation of the forward end of one hood section and the corresponding clip 14 separated.

Referring to these drawings, it will be seen that my improved incinerator comprises hood sections 10, which are spaced from each other and extend upward and thentoward each other, the inner edges of the hoods being spaced from each other to leave a longitudinally extending slot 11, as shown most clearly in Fig. 5. The side walls 10 are connected to each other at their front ends by a transverse bar 12 having angularly bent extremities "13. Attached to these angular extremities are strips of metal 14, which are folded upon themselves to provide two spaced side walls and the clips thus formed embrace the side walls 10*, as shown clearly in Fig. 5, the side walls being pivoted or otherwise hinged to these clips. The hood sections may be braced from each other in.

any other desired manner, and I do not wish did to be limited to the construction illustrated.

Swingingly mounted between the side walls 10 as illustrated in Fig. 4, are the front and rear walls 16 and 15. Each of these walls 15 and 16 at its upper edge is formed to provide a bead 17 engaging a transversely extending pintle 18, which is supported in the side walls and also passes through the clips 14:, as illustrated most in Fig. 4:, these forward and rear walls 16 and 15 are free to swing rearward to any desired extent, as the machine is drawn over clearly in Fig. 5. As shown in'dotted lines is transversely flat and extends downward to the lower-end of the generator and is attached thereto in any. suitable manner, but is shown as attached thereto by means of a U-shaped clip bolt 21. This vapor generator comprises, as illustrated in Fig. 8, a closely coiled pipe 22, the inlet end of this pipe being connected to a source of fuel, the outlet end of the pipe extending of clearly in Fig.4. The draw bar 29 may be tivator or other wheeled upward and being engaged with a burner proper 23' comprising a rectangular casing or head having an opening discharging downward through the coil, this head 23 being spaced from the top of the coil a suflicient distance to permit proper admixture of air with the escaping vapor.- The flame projected downward from this head 23 vaporlzes the fuel within the coil 23 and the flame is discharged against the ground as illustrated clearly in Fig. 3.

The pipe 24, which connects with the coil, extends forward and-then upward to a tank 25, which contains the fuel, there being a flexible section 26 between the pipe 24 and the fuel tank 25. The passage of-fuel from the tank 25 into the pipe 24: is controlled by a needle valve 27 and the fuel is positively forced into the generator and burner by compressing air in the'upper portion of the tank by means of the air pump 28. For the purpose of dragging the incinerator behind a cultivator, I provide a draw bar 29, which extends rearward and then downward and slightly forward, and is connected to the bar 12 in any suitable manner, as by a bolt 12 and bracket 19 extends forward and is attached to the downwardly extending end the draw bar 29, as illustrated most in the form of a cultivator beamor may be one of the cultivator beams of the machine, and I have shown it as such. The cultivator A may be of any suitable or ordinary construction and I, of course, do not wish to limit myself to the particular form of culframe which is used for the purpose of dragging the incinerator between the rows of plants.

. For the purpose of knockinginsects off of the plants and into the path of the incinera tor, I provide means suspended upon the frame of the cultivator in advance of the incinerator, which will strike the plants and deflect them sharply and suddenly over toward the lineof travel of the incinerator and for this purpose -I have shown the swinging boards 30, there being two of these boards, of the machine, and these boards being inclined forward and outward so that when they strike the plants, the plants will be forced inward and throw the insects toward the middle plane of the machine. These boards or equivalent instrumentalit'es are preferably supported from the frame of the thereof. These shield The as illustrated in Fig. 1, on each side' ..the plants or strip the leaves therefrom as would chains or'like devices.

In order'to prevent the plants from striking the very highly heated walls of the incinerator, I provide a series of shield rods 32. which arch over the body of the incinerator, preferably at the outer upper corners rods 82 are not sup ported at their rear ends, but at their forward ends they extend downward and each set of shield rods is supported upon a bolt 33 passing through the bar 12.

The operation of this incinerator will be clear from Fig. 3. The insects are knocked off into the path of movement of the incinerator. As the incinerator passes over them, they are subjected to the intense heat within the oven or incinerator and to the direct action of the flames which are discharged against the ground from the burner and deflected laterally. Inasmuch as the constitutes the pintle for the forward wall 16 and thus these hood sections will ride over the ground and rise and fall with irregularities in the ground. The U-shaped clips 14 are-rounded off at their lower front ends, thus allowing them to more easily drag over an obstruction and at the same time protect the front ends of the side walls 10 as these side walls are made of light sheet; metal and would become easily deformed by striking obstacles if it were not for the protection afforded bythe U-shaped clips. These side walls of the hood sections, as well as the end walls, are made from about #18 gage s'heet iron and no wood or other combustible material is used in the construction of the oven. pivoted end walls 15 and 16 swing freely and drag along the. surface of the ground, while the side walls of the hood sections are dragged along in a shallow furrow formed by the U-shaped clips. The oven or incinerator is made very flexible in its connections, so that itwill adjust itself to uneven ground. The draw bar 29 is so connected to the cultivator frame that the rear end of the draw bar may rise and fall and the lever a on the cultivator frame A is connected by a rod or other suitable connection to the beam 29 so as to permit the oven to be raised when traveling to and from the place where it is to be used or when t eater lever suitable for the purpose which may be found upon an ordinary cultivator may be used or the cultivator may be provided with a special lever for the purpose. The connections between the lever and the beam 29 will, of course, vary with the difi'erentmakes of cultivators. It will be also noted that the beam 29 is connected to the cross bar 12, which is of relatively heavy material and that the bracket19 is also connected to this cross bar and thus no strain comes upon the hood sections of the oven, permitting these sections to rise and fall freely and to conform to the surface of the ground over which they move. I

The invention is very simple, has been found thoroughly efiective'in practice, and is much more destructive of insect life than merely knocking the insects into collecting pans from which they are liable to escape.

While I have illustrated a form of my invention which I have found in practice to be extremely efiective, it will be obvious that the details of construction may be modified in many ways without departing from the spirit of the invention and that the device may be made and arranged to suit various forms of cultivators or that it may be drawn over the ground by other means than by attachingto a cultivator.
